Pretty underwhelmed with the bass output of the Harmon Kardon system. Decided to grab a retrofit subwoofer harness from Technic PnP and a cheap spare tire sub off of amazon. All-in I'm around a $350 investment.

Speaker install was a breeze with the battery and chassis grounding points being directly adjacent in the trunk. Confirmed the unit powers on but waiting on the PnP harness to show up in the mail today. Will report back on sound quality if anyone is interested.

I have a hunch I'll end up returning the Rockville woofer and replacing with the more expensive JBL but maybe the Rockville will surprise me....

Initial Reaction: Don’t know why I was expecting more from a $200 speaker 😂. Managed to get decent sound out of it after tweaking some settings, but don’t think this one is a keeper.

Wanted to follow up after a week or so. Still planning on swapping out in the future, but there appears to be a break-in period with the speaker.

I'm sure my ears/expectations have also adjusted since install, but the sub doesn't sound half bad now. It's punchier and overall cleaner throughout the lower frequency bands. Still not the solution for an audiophile, but well worth the $200 if all you're looking for is some decent bottom end and an easy install.

You would be better off, replacing the front speakers, including the base under the seats and adding an amp that will give your true sound Quality you’re looking for the hk only has about 463 watts from factory

How is your Subwoofer project going?
Can I ask what you ended up doing?
Have you found a solution that you are happy with?

Ditto, but that's an interesting set up you did there...

To be honest, I’ve left it as is. I’ve had a number of compliments from friends thinking it was the stock stereo setup and how good the bass was. Hands down the setup sounds significantly better than from first install too. Once the speaker has broken in, it really does sound pretty good.

I am in a similar boat. I ended up adding a Match 10DSP/Amp, exchanged the underseat Woofers. The sound is amazing, but the low end is still lacking.
I don't want to fill up the trunk with a gigantic Sub, so the Spare tire space is what I am looking at.

I know that installing the Sub in the Spare tire area is not ideal... but I hope that the sound would still be much better than without it.

I went through the oem+ upgrades in my last bimmer and was never really satisfied with performance vs the cost. Happy with the decision I made here.
